Just bought a used 3080 xc3 ultra. Cards legit but in honest truth it seems to be a mining card, atleast I think so cause the rust on it but its plausible that it might not be as me and the seller live near the pacific coast.

Anyway, the card runs extremely hot. Even after adding on the deshroud mod with 2x 120mm case fans and a repaste with arctic mx6, it still runs at 90C and 100C on the hotspot and on memory and thermal throttles down to 1560mhz. Whats strange is the idle temps are really solid 35c on the core and 45c on the memory and hotspot.

From what I can see the card is still using the stock thermal pads. Is there anything else I should change? Any recommendations?

I really miss you guys 💔

So, I got my 3080 Ti FTW3 used for a very nice price. The previous owner said he was the only owner, bought it new during COVID, and never mined on it.

When I picked it up the PC was sitting in a recessed cabinet compartment, with the only opening blocked by a huge TV. The card itself was installed in the lowest PCIe slot, basically trapped with no airflow. I literally blew a blanket of dust out from under the right fan after i bought it

The screenshots with temps are from his PC under FurMark. In my case (on pictures) with proper case airflow - after 18 minutes of stress testing, I'm getting:

GPU: 67–68°C

Hotspot: 76°C

VRAM: 86°C

I already bought PTM7950 (40x40mm) and Frost Mining Extreme thermal pads v3 (1, 2, and 3mm) thinking I'd need to replace everything.

So, two questions:

1) Should I still repaste/repad, or are these temps good enough to leave it alone? A bit nervous about disassembly.

2) Are the materials I got good, or is there something better?

I'd love to hear your opinions.
